Her obituary reads like it was written by a funeral home staff member who knows little about Catholics, whether "novus ordo" or "traditionalist".  The obituary, besides providing the times and place for the visitation and the Mass, is a last opportunity to witness the faith by the decedent, which might bear fruit among those who read it. 

Though that apparently wasn't the case here, I have to think that funeral homes just use the verbiage "Mass of Christian Burial" because that is what Newchurch calls it, and they're just following procedure.   There's probably some book of protocol, or something like that, for the nomenclature of various religions.
